Question

(x4 − 9x + 5x7) + (5x − 10 + 3x4 − 2x2)

Answer 1

Simplify:
(X^4 - 9X + 5X^7) + (5X - 10 + 3X^4 - 2X^2)

= X^4 + - 9X + 5X^7 + 5X + - 10 + 3X^4 + - 2X^2

Combine Like Terms:
= X^4 + - 9X + 5X^7 + 5X + - 10 + 3X^4 + - 2X^2

= (5X^7) + (X^4 + 3X^4) + (- 2X^2) + (- 9X + 5X) + (- 10)

= 5X^7 + 4X^4 + - 2X^2 + - 4X + - 10

Answer is: 5X^7 + 4X^4 - 2X^2 - 4X - 10

Answer 2

= x^4 - 9x + 5x^7 + 5x - 10 + 3x^4 - 2x^2

Adding like terms :-

= 5x^7 + 4x^4 - 2x^2 - 4x - 10 (answer)
